在socket.io中获取邮件发件人的客户端ID？

on the server side i got

在服务器端我得到了

socket.on('chat', function (data) {
    io.sockets.socket(data.clientid).emit('chat', {
        msg: data.msg,
        senderid : senderid
    });
});

How can I get the get the senderid without the sender having to post their clientid through with the message?

如果没有发件人必须通过邮件发布他们的clientid，我怎样才能得到发件人？

It turns out I can just use socket.id of the user sending through a msg to get their clientid, such as:

事实证明我可以使用用户通过msg发送的socket.id获取他们的clientid，例如：

  socket.on('chat', function (data) {
      io.sockets.socket(data.clientid).emit('chat', {
          msg: data.msg,
          senderid : socket.id
      }); 
  });

Originally I thought I could just fetch the clientid by doing :

最初我以为我可以通过这样做来获取clientid：

  io.sockets.on('connection', function (socket) {
     clientid = socket.id;

But clientid will be the last person who connected in this instance, not the last person who sent through a chat

但是clientid将是最后一个在这种情况下连接的人，而不是通过聊天发送的最后一个人

I'd suggest sending over a username (make sure it's unique) and keeping an object of client ids associated with usernames in memory.

我建议发送一个用户名（确保它是唯一的）并保留一个客户ID的对象与内存中的用户名相关联。
